Hibernate using TuxOnIce working intermittently

In my numerous attempts to get hibernate to work well and respond fast, I have turned to using TuxOnIce with the linux-pf kernel, as detailed in the Wiki page.

I have noticed the following: When I use an amount of RAM > around 1 GB (and 0 kB of swap used), the hibernate seems to work all right- with a message like

Seeking to free __ MB of memory

(and no error until it powers off)- but the resume fails, getting stuck at the message:

Doing atomic copy/restore

I thought the issue was that of a previous image existing in my swap partition, so I decided to issue a command to erase the image by doing

echo 0 > $tuxonice_sys/image_exists

in my sleep hook for systemctl (as is described here). Here is the file:

$ sudo cat /usr/lib/systemd/system-sleep/tuxonice-userui.sh 
#!/bin/bash
# /usr/lib/systemd/system-sleep/tuxonice.sh

tuxonice_sys="/sys/power/tuxonice"
tuxoniceui_cmd="/usr/sbin/tuxoniceui"
tuxoniceui_vt=63
tuxoniceui_original_vt="/run/tuxoniceui_original_vt"

if [ "$1" = "pre" ]; then

    echo `fgconsole` > $tuxoniceui_original_vt
    chvt $tuxoniceui_vt

    if [ -d $tuxonice_sys -a -x $tuxoniceui_cmd ]; then
        if [ -c /dev/fb0 -a -d /etc/splash/tuxonice ]; then
            tuxoniceui_opt="-f"
        fi
	echo 0 > $tuxonice_sys/image_exists
        echo $tuxoniceui_cmd $tuxoniceui_opt > $tuxonice_sys/user_interface/program
    fi
fi


if [ "$1" = "post" ]; then
    chvt `< $tuxoniceui_original_vt`
    rm $tuxoniceui_original_vt
fi

It still failed to resume when using systemctl to hibernate. Note that both hibernate and resume work perfectly when there is no message like that about seeking to free some memory. I can resume from hibernate in about 10 seconds to see an equally responsive computer, unlike what I see with other methods.

Next, I tried using the hibernate-script method developed by the TuxOnIce developers. Now I see a different behaviour- Hibernate again works perfectly when the RAM used is about less than 1 GB, but when there is the message about freeing memory, this time the hibernate itself fails. It freezes when trying to hibernate and I have to manually power off the laptop.

The obvious inclination is that my swap is not sufficient, but it seems to be- I have 4GB RAM and my swap partition is 4.4 GB. In my desperation to solve this, I even created an 8 GB swap file specifically for use with TuxOnIce, but it only seems to have moved the threshold up to 1.2 GB.

For reference, I am using an HP Pavilion dv6-6115tx with the open source drivers. I can post logs when it works. But when it fails, journalctl does not show any records from the time of the crash because I manually power my system down.

I am thinking of trying out the option ImageSizeLimit, but am not sure how much of an impact it will have on my response times and whether it will fail if my RAM is full and overflowing with data. Has anyone used this option with success?

Thanks!

#       If you do not wish to patch your kernel but still be able to suspend to

## Any other /proc/software_suspend setting can be set like so:

## For filewriter:
# FilewriterLocation /suspend_file 1000
# VerifyFilewriterResume2 yes

## Specify a userui like this:
ProcSetting userui_program "/usr/sbin/tuxoniceui"

# Scale CPU to full speed to make sure we suspend as fast as possible.
